The left likes to use words to mean their opposites. Communist dictatorships like to call themselves “democratic” republics. It’s a cynical tease, because it shows that they know democracy is better than dictatorship.

A cynical lefty euphemism much in use in America is “diversity”. It should mean “variety”, but what it has come to mean in practice is its opposite – “orthodoxy”: a strict doctrinal uniformity of opinion.

The doctrine has achieved enormous success in the universities, which are no longer open to new ideas, no longer allow free debate, no longer question fixed assumptions. That’s what they once existed for. Now they are temples of political correctness, safes for the secure locking up of leftist doctrine.They want a sterile mix of ethnicities and of as many genders as semantic ingenuity can invent, but not a fertile mix of ideas. They recognize only one set of ideas as correct. To question it is heresy.

Steps towards enforcing this kind of “diversity” in the news media have been proposed by the Obama administration. Charles Krauthammer deplores the move in this video clip:

Diversity has become corporatized on American campuses, with scores of bureaucrats and administrators accentuating different pedigrees and ancestries. That’s odd, because diversity does not mean any more “variety” or “points of difference,” at least as it used to be defined.

Instead, diversity has become … synonymous with orthodoxy and intolerance, especially of political thought.

When campuses sloganeer “celebrate diversity,” that does not mean encouraging all sorts of political views. …

Do colleges routinely invite graduation speakers who are skeptical of man-made global warming, and have reservations about present abortion laws, gay marriage or illegal immigration – if only for the sake of ensuring diverse views?

Do we really want all institutions to weigh diversity rather than merit so that coveted spots reflect the race and gender percentages of American society? …

Gender disparity is absolutely stunning on American campuses. Women now earn about 61 percent of all associate degrees and 57 percent of all bachelor’s degrees. With such disproportionate gender representation, do we need outreach offices on campus to weigh maleness in admissions? Should college presidents investigate whether the campus has become an insidiously hostile place for men? …

If ethnic, rather than class, pedigrees provide an edge, how do we ascertain them in today’s melting-pot culture? Does the one-quarter Latino student, the recent arrival from Jamaica or the fourth-generation Japanese-American deserve special consideration as “diverse”? And if so, over whom? The Punjabi-American? The Arab-American? The gay rich kid? The coal miner’s daughter? Or the generic American who chooses not to broadcast his profile?

Does Diversity Inc. rely on genetic testing, family documents, general appearance, accented names, trilled pronunciation or just personal assurance to pass judgment on who should be advantaged in any measurement of diversity?

In such an illiberal, tribally obsessed and ideologically based value system, it is not hard to see why and how careerists such as Sen. Elizabeth Warren and activist Ward Churchill were able to fabricate helpful Native American ancestries.

Diversity came into vogue after affirmative action became unworkable in the 1980s. Given the multiplicity of ethnicities, huge influxes of new immigrants and a growing rate of intermarriage, it became almost impossible to adjudicate historical grievances and dole out legal remedies. So just creating “diversity” – without much worry over how to define it – avoided the contradictions.

But diversity is not only incoherent; it is also ironic. On a campus short of resources, the industry of diversity and related “studies” classes that focus on gender or racial differences and grievances crowd out exactly the sort of disciplines that provide the skills – mastery of languages, literature, science, engineering, business and math – that best prep non-traditional graduates for a shot at well-compensated careers.

Cancel the philosophy courses, people. Oh, and we’re going to be shuttering the political science, religion and pre-law departments too. We’ll keep some of the English and history folks on for a while longer, but they should probably keep their resumes handy.

Because, you see, they are of no use anymore. We have the answers to the big questions, so why keep pretending there’s anything left to discuss?

At least that’s where Erin Ching, a student at Swarthmore College, seems to be coming down. Her school invited a famous [or infamous – ed] left-wing Princeton professor, Cornel West, and a famous right-wing Princeton professor, Robert George, to have a debate. The two men are friends, and by all accounts they had an utterly civil exchange of ideas. But that only made the whole thing even more outrageous.

“What really bothered me is, the whole idea is that at a liberal arts college, we need to be hearing a diversity of opinion,” Ching told the Daily Gazette, the school’s newspaper. “I don’t think we should be tolerating [George’s] conservative views because that dominant culture embeds these deep inequalities in our society.”

Swarthmore must be so proud.

Over at Harvard, another young lady has similar views. Harvard Crimson editorial writer Sandra Y.L. Korn recently called for getting rid of academic freedom in favor of something called “academic justice”.

“If our university community opposes racism, sexism and heterosexism, why should we put up with research that counters our goals simply in the name of ‘academic freedom’?” Korn asks.

Helpfully, she answers her own question: “When an academic community observes research promoting or justifying oppression, it should ensure that this research does not continue.”

One could easily dismiss these students as part of that long and glorious American tradition of smart young people saying stupid things. As Oscar Wilde remarked, “In America the young are always ready to give to those who are older than themselves the full benefits of their inexperience.”

But we all know that this nonsense didn’t spring ex nihilo from their imaginations … These ideas are taught.

Indeed, we are now up to our knees in this Orwellian bilge. Diversity means conformity. …

To want “diversity” – the writer sums up – means to listen only to “people who agree with me” and that means people who are left wing.

[For] the sages of Swarthmore and Harvard … if the conversation heads in a direction where [they] smell “oppression” – as defined solely by the left – then it must not be “put up with”.
